Complete infrastructure reorganization to role-based structure

- Created all missing admin pages (users, settings, events, members, payments)
- Created board pages (governance, meetings)
- Updated dashboard router to use new /admin, /board, /member structure
- Added isMember alias to useAuth composable for consistency
- All pages now use correct role-based layouts and middleware
- Build verified successfully

The platform now has a clean separation:
- /admin/* - Administrator dashboard and tools
- /board/* - Board member governance and meetings
- /member/* - Member portal and resources

Next steps: Complete remaining member pages and clean up old dashboard files
